Enforce default rapt keystore config values

[Ayowel]

Since Ren'Py 8.1.0, Ren'py does not provide default project config, hence the enforcing of default values if none is set.

Additionally, we want to check for the file's content as Ren'Py rebuilds those config files if the some options are not set in the android config.
